Kumiko vs Magnet
Magnet has been the Mac App Store pick for window snapping for over a decade. Here is where it shines and where Kumiko does more.
Updated
Short answer: Magnet is a fine, inexpensive snapper from the App Store. Kumiko costs more because it arranges the whole screen, restores what you had open and takes requests in plain words.

What Kumiko adds
- Arrow keys that know your screen. Hold ⌃⌥ and press ← or →. Press again to go from ½ to ⅔ to ⅓. On a 21:9 or 32:9 ultrawide the first press gives a third, and ↑ gives you the centre column.
- Six layouts for the whole screen. Focus centre, Halves, Thirds, Studio, Stack and Columns place every window at once with ⌃⌥1 to ⌃⌥6.
- Resume. Close the lid and Kumiko brings back every browser tab, the project folder in your editor and the folder each terminal was in. It works with 45 apps.
- The AI command bar. Press ⌥ Space and type "review PR 482 and reply to the team". Kumiko picks the windows, opens what's missing, brings the right tab forward and shows you the plan first.
- Meeting and Share-safe. Calls move under your camera with notes below; private apps blur when you share your screen.
Which one should you pick?
Pick Magnet if
You want the cheapest decent snapper and you only buy from the Mac App Store.
Pick Kumiko if
Your screen is big enough that placing windows one by one is the slow part.
Kumiko is €30 once for 2 Macs, and the first 25 launch licences are €9. It works on macOS 14 or later.
